If you like magic with playing cards, you should check out Magic Poker Flip – a neat little magic app for Android.
Developed by XDA forum member jonathanlu, Magic Poker Flip has a slight twist in that you must work out the trick behind the app before you can use the magic on your friends!
When you launch Magic Poker Flip you are greeted with a blank screen. Flip your Android device down and up and you will be presented with the back of a playing card. The idea is that your friends pick a card from a real deck or pick one in their heads and write it down….. and when you swipe across the touchscreen, voila – the card that flips over is the one that they have chosen. Magic!
The secret of the trick is hidden inside the app, so in order to demonstrate this to your friends, you’ll have to figure it out for yourself first.
When you think you’ve solved the trick, email the developer and he will confirm if you have the correct solution.
Try it out for yourselves – be sure to post a comment if you’ve solved it! Magic Poker Flip is available for free in the Market.
